(A) The balanced chemical reaction is:$2 MnO_{4}^{-} + 5 SO_{3}^{2-} + 6 H^{+} \rightarrow 2 Mn^{2+} + 5 SO_{4}^{2-} + 3 H_{2}O$From the balanced chemical equation,we can observe that:$5$ moles of $SO_{3}^{2-}$ react with $2$ moles of $KMnO_4$.Therefore,$1$ mole of $SO_{3}^{2-}$ reacts with $2/5$ moles of $KMnO_4$.Hence,the correct option is $A$.
